State of New York,-have invented certain new and useful'lmprovements in Temporary Binders, of which the following is a specification.

This invention relates to temporary bind- IQ ers for loose sheets, and has for its object to [produce a binder 'thatis simple and strongiri construction and made of few parts that are readily assembled and operated. In the drawings, Figure 1 is a view of the binder from below when the binding-prongs are closed, the bottom and top plates being removed. Figs. 2 and 3 are cross-sections on the line 2 2 of Fig. 1, showing-the prongs open and closed, res ectively. Fig. 4 is a the line 4 4 of Fig. 3. Fig. 5 is a horizontal section on the line 5 5 of Fig. 7 and shows a modified form of binder. Figs. 6 and '7 are cross-sections on theline e fi'efhhig 5-, showing the prongs open and as closed, respectively. Fig. 8 1s a vertical'section on the line 8 8 of Fig. 7. Fig; .9 isatop plan view and shows another modif ed form of binder. Figs. 10 and 11 are cross seetions on the line 10 10 of Fig. 9 looking toward the left and showing the prongs open and closed,

respectively. Fig. 12 is a longitudinal section on the l'ine 12-12 of Fig. 11. Fig. 13 is a horizontal section on the line 13 13 vof Fig. 15 and shows. still another modified form of binder. Figs. 14 and 15 are cross-sections on the line 14 14 of Fig. 13 looking toward the left and showing the prongs open and closed, respectively. Fig. 16 is a vertical section on the line 16 16 of Fig. 15. Fig. 17

is a horizontal section on the line 17 17 of Fig. 18. Fig. 18 shows the binder adapted to a filing-board. Figs. 19 and 22 show a key used in one form of the binder. Fig. 20 is a vertical section on'the line 20 20 of Fig.

by throwing the prongs 1 and 2in andout of engagement with the prongs with which they mate, respectively, and a similar arm 7 on theshaft 5 fulfils a similar function with referience to the prong 4.

A perforations through which't'he' arfnsh and 7 extend and rotatively support the shafts 3 and 5 in position within the hollow rib of the plate 8, which is bent part way around said shafts, respectively. The prongs are operated by means of the plate 10, which is" movable transversely with reference to the plane of the movement of the prongs and" which has inwardly-directed diagonal'slots- 11 and 12, adapted to receive the arms 6 and 7, respectively. The outer ends"11% and 12 of the slots 1.1 12, respectively, are extended in the direction of themovement of the plate lie between the Theplate Qhas 10. The operating-plate 10 isretained in place by the bottom plate 13, which in turn is locked to the outer edges of the top plate 8 The prong 17, which is oppositeth-e' prong 4,

is attached to another rock-shaft, like the in'dotted lines as 18 in Fig. 1. H and 18' are also rotatively sup-ported'upon the late 9 within the rib 16-1; of said plate 8, an'd' This last-mentioned shaft is shown-.

spectively, in the straight extensions 11%,, 12%;, 2111-, and 229 of the slots, theprongs are closed and so looked that they can only be opened by moving the operating plate till the arms lie in the diagonal parts of the slots.

An extension-plate 23 may be attached to the operating-plate by suitable means, as by a pin 24 on one of the parts that enters a slot 25 in the other.

Figs5 to 8, inclusive, show two pairs of mating prongs and represent those on one of the sides of the binder as stationary, so that the binder is opened by tilting back the prongs on one side only. In Figs. 6 and 7 the prong26 is stationary and the prong27 adapted to swing- The stationary prongs and the swinging prongs,.respectively, are both represented in all the figures of, the drawings as formed in one piece Withthe horizontal shaft. In Figs. 5 to 8, inclusive, the shaft 28, from which the stationary prongs rise, is secured in place between the plates 29 and 30 of the binder by soldering or in any other vsuitable manner. Theshaft 31 of the swinging prongs is rotatiyely supported between said plates, which form a 'casing that is oval in cross-section, and Withina portion 30-}- of the plate 30, bent around said shaft.

Said shaft has upon it an arm 3?,py which it is rocked and which in F 1g. 5 s sl form of a bend in the shaft.

In the construction shown inFigs. 5 to S,

inclusive, the rocking arm 31, that carries the swinging prongs, is operated by a bar 33. Fig, 8 shows the bar rotatiyely supported in downwardly-1)rojecting ears 34 and 35 on the upper plate 30. arm 32 on the rocking shaft 31 and is thicker. through in one dimension than the other, so

. that when it lies in'the position shown in Fig.

6, in which the greater thicknessis in the Vertical plane,it bears down'upon the arm 32 till it forces the swinging prongs into engagement, respectively, with the opposite stationary prongs; but when the bar 33 is turned over into the position shown in Fig. 7, in which its thinner dimension hes in the vertical plane, the swinging prongs are free to swing away from the stationary prongs, and

so to open the binder. A spring 36 tends nor-' mally to keep the arm 32 of the root-shaft m own in the The bar 33 lies above the I i above the arms and 57 in ears on the plates erases contact with the operating-bar 3th Said bar is operated by the handpiece 3?, which is err-- tensible for that irpose, hire the operating plate described in connection Wm). the figures first describedl l v The construction shown in Figs. 9- to .12,

inclusive, differs from that last deseribe'd in that in this construction the prongs on both sides of the binder are adapted to swin r and that the prongs are both opened and osed by the positive action of the operatin -rodQ In this construction the rocking shafts and 47 are supported Within the casing formed by the top plate 39 and the inter operatingbar is thicker in one dimension than the other. The rocking shaft 42, cars rying the tilting prongs 43 and 44, has two arms. When the prongs are closed, as shown in Fig. 11, one, 45, of these arms is vertical, and the other, 46, is horizontal. The other rock-shaft 47, carrying the prongs and 49,

also has two arms, one, 50, of which, is yertical and the other, 51, is horizontal whenthc prongs are closed. The operating-bar 38 hes below the horizontal arms 46 and 51. and be" tween the ver ticalarms 45 and 50. The di mensions of the operating-rod are such that i When it lies in one position it raises the horizontal arms 46 and 51 and releases the ver't ical arms 45 and 50, thereby opening the binder, asshown in Fig. 10, and when it is turned over itforces out the vertical arms 45 and 50 and releases the horizontalarms 46 and 51,

1 thereby closing the binder, as sh own in Fig. 1. 1

Figs. 1 3 to 16, inclusive, show a construction that differs from that of Figs. 5 to 8, inclusive,

in that in this construction the prongs in both sides of the binder are adapted to-tilt and that a spring of another form is employed. In this construction the shaft 52, w the tilting prongs 53 and 54,has an iun'arr extending arm 55, by which. it is rockedf other shaft 56 has a similarly inwardly tending arm 57, by which it is rocked. An operating-bar 58 is rotatively supported 58 and 59. Springs 60 and 61 tend to force the arms up, and thereby'to tilt the prongs'open, as shown in Fig. 14. The springs are tongues on the plate 59. The operating-bar 58 is thicker in one dimension than the other and when turned intoone positionreleases the arms 55 and 57, so that the springs or} and can raise them, and thereby tilt the prongs open. (see Fig. 14) and when turned into the other direction forces down the arms 55 and 57, and thereby closes the prongs. (See it 15.) The rod 58 is operated by the hand piece 62.

While a spring is shown in some of 5 111 a loosevleef'binder, the combination Within, icas'i'ng'eonlprisinga 'bzise having laterallyoverlappingfia nges onits longitudinal edges, and a plate or strip haying its edges 'nonfined to the "base by the said flanges, of
